Effectiveness of limited plasma exchange in Guillain-Barré syndrome.

YANGON (Myanmar); MYANMAR

Objective: The aim of this study is to compare the efficacy of limited plasma exchange against supportive and standard treatments in treatment of Guillain-Barré syndrome (GBS). Method: A total of 90 GBS patients admitted to Yangon General Hospital, Yangon, Myanmar were recruited over 1.5-year-period from January 2017 to June 2018 and they were divided into 3 groups according to the treatment they received (convenience sampling method): supportive (n=36), limited plasma exchange (LPE) (n=35) and standard (therapeutic plasma exchange - TPE or IVIg) (n=19)). Their clinical features, electrophysiological subtypes and severity were compared at baseline, and outcome (change in GBS disability score (GDS) at 30 days after entry) was assessed and compared. Results: Baseline characteristics such as gender, GBS subtypes and respiratory involvement were comparable, but standard treatment group had older patients, and LPE group had shorter latency to nadir and more cases with antecedent diarrhea, which are poor outcome predictors. At 30 days from entry, mean GDS improvement was 0.9 + 0.6 in supportive, 1.4 + 0.6 in LPE and 1.2 + 0.8 in standard treatment groups respectively. The difference between LPE and supportive treatment was statistically significant (p 0.002) but there was no difference between LPE and standard treatment (p = 0.512). Regarding untoward effects, apart from one transient hypotension and 2 anemic cases, no other serious adverse effects were noted from LPE therapy. Conclusion: LPE may be superior to supportive treatment and may not be inferior to standard treatment. Therefore, LPE may be an alternative effective treatment for GBS patients who are not accessible to standard treatments especially in low income countries with limited resources.
